LegiScout: A Visual Tool for Understanding Complex Legislation

Abstract: Modern legislative frameworks, such as the Affordable Care Act (ACA), often involve complex webs of agencies, mandates, and interdependencies. Government-issued charts attempt to depict these structures but are typically static, dense, and difficult to interpret—even for experts. We introduce LegiScout, an interactive visualization system that transforms static policy diagrams into dynamic, force-directed graphs, enhancing comprehension while preserving essential relationships. By integrating data extraction, natural language processing, and computer vision techniques, LegiScout supports deeper exploration of not only the ACA but also a wide range of legislative and regulatory frameworks. Our approach enables stakeholders—policymakers, analysts, and the public—to navigate and understand the complexity inherent in modern law.

The central panel displays the interactive, force-directed legislative-organizational graph (LOG), where users can click on nodes to highlight immediate relationships. On the left, a scrollable list of entities provides quick access to major organizational actors within the legislation; selecting one centers the graph on its connections. On the right, a glossary offers filterable categories describing the roles and attributes of each node. At the top left, a search bar enables users to enter legislative terms—such as ”appropriation” or ”mandate”—and highlights relevant nodes through BERT-assisted semantic linking.
